can you install spybot without having an internet connection, 1.3 use to but 1.62 does not.

my problem is i had a dns changer virus infected a machine that was not protected, virus is killed now, but all the settings in registry and elsewhere for DNS remains, so cant install cause spybot installer wants to contect to internet, which i cant do.
i have scan regisrty etc for ip, but they keep coming back, latest macafee vius s/w installed now
